Bats and dolphins emit sounds and interpret echoes to navigate and hunt.
Bats emit ultrasonic calls (20 to 200 kHz) and process echoes to detect prey size and location. Dolphins use clicks focused by the melon and receive echoes through the lower jaw. Some moths evolved hearing and jamming clicks in response.
Calls are shaped to environment. Doppler shift compensation is used by some bats. Moths evolved defences.
Example: dolphins detect fish buried in sand.
